DB2J31000L Datasheet/PDFThe DB2J31000L diode is a high temperature, rated reverse voltage Schottky diode. It provides the optimal solution for high temperature, high frequency circuits where the Schottky diode exhibits excellent losses over pulse conduction time.
The DB2J31000L diode is a single diode with a reverse voltage capability of up to 30 volts and a forward voltage drop of 0.5 volts max. Its forward current is 1 amp max at 25 degrees Celsius and a continuous operating temperature range of -55 degrees Celsius to +150 degrees Celsius. Its construction involves a junction of a PN-diode with a metal rectifier making it a highly reliable single diode.
The DB2J31000L diode is of the surface mount type and has a flat type molded-packaging construction, which is solderable and also has ESD protection. It also has very low forward voltage drop, fast switching speed, no reverse recovery current and more than adequate surge capability.
The major field of application of the DB2J31000L diode is in high temperature environments with high frequency applications. It is mostly suitable for surge protection circuits, Schottky rectifiers, serial and relay power supplies and for EMC filtering. It is also ideal for automotive applications, high temperature control, AC adaptor circuits, high speed motor control circuits and current sensors.
The DB2J31000L diode works on a simple principle of voltage division, which allows it to divide the applied voltage into two parts, one of which is the rectified voltage, and the other being the sum of forward and reverse bias voltages. When the anode voltage is positive compared to the cathode voltage, the Schottky rectifier is forward biased, allowing current to flow through the diode. When the anode voltage is negative compared to the cathode voltage, the diode is reverse biased, blocking current flow through it.
The DB2J31000L diode also has a built-in protection mechanism to prevent current overloads due to surge conditions. This protection mechanism works on the principle of automatic shut-off, preventing further damage to the device and circuit, and providing a safe working environment.
